Suggested Maximum Speed in Each Gear
Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the high-
est gear suggested for that speed. Always observe post
ed speed limits and drive according to the road condi-
tions to ensure safe operation. Do not over-rev t he engine when shifting to a lower gear as it may cause
engine damage or loss of vehicle control.
PERMANENT DIAGNOSTIC TROU BLE CODE (PERMANENT DTC)
Permanent DTC is defined in SAE J1979/ISO 15031-5 Service $0A.
ECM stores a DTC issuing a command of turning on MIL as a permanent DTC and keeps storing the DTC as
a permanent DTC until ECM judges that there is no presence of malfunction.
Permanent DTCs cannot be erased by using the Erase function of CONSULT-III or Generic Scan Tool (GST)
and by disconnecting the battery to shut off power to EC M. This prevents a vehicle from passing the state
emission inspection without repairing a malfunctioning part.
When not passing the state emission inspection due to more than one permanent DTC, permanent DTCs
should be erased, referring to this manual.
NOTE:
• The important items in state emission inspection are t hat MIL is not ON, SRT test items are set, and perma-
nent DTCs are not included.
• Permanent DTCs do not apply for regions that permanent DTCs are not regulated by law.
Permanent DTC Item
For permanent DTC items, MIL turns ON. Refer to EC-542, "Emission-related Diagnostic Information", “EMIS-
SION-RELATED DIAGNOSTIC INFORMATION ITEMS”.
Permanent DTC Set Timing
The setting timing of permanent DTC is stored in ECM with the lighting of MIL when a DTC is confirmed.

How to Erase Permanent DTC
When a DTC is stored in ECM• When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shutoff if the same mal-
function is not detected after performing the drivi ng pattern for MIL shutoff three times in a raw.
When a DTC is not stored in ECM
• The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.
×: Applicable —: Not applicable
*: For group, refer to EC-542, "Emission-related Diagnostic Information", “EMISSION-RELATED DIAGNOSTIC INFORMATION
ITEMS”.

• When the same malfunction is detected regardless of driv ing conditions, reset the counter of driving pattern
B.
• When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving pattern B.
Driving Pattern D
• Driving pattern D means operating vehicle as per the following.
- The state of driving at 40 km/h (25 MPH) reaches 300 seconds or more in total.
- Idle speed lasts 30 seconds or more.
- A lapse of 600 seconds or more after engine start.
CAUTION:
Always drive at a safe speed.

< SERVICE INFORMATION >[MR18DE]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
If the MIL does not light up, refer to DI-21
or see EC-1033.
2. When the engine is started, the MIL should go off. If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by MIL lighting up when there is
malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine cont rol system malfunctions and MIL circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected, and demands the
driver to repair the malfunction.
MIL Flashing Without DTC
When any SRT codes are not set, MIL may fl ash without DTC. For the details, refer to EC-542, "Emission-
related Diagnostic Information".
HOW TO SWITCH DIAGNOSTIC TEST MODE

•It is better to count the ti me accurately with a clock.

This function checks the MIL bulb for damage (blown, open

If the MIL does not come on, check MIL circuit.
Engine running MALFUNCTION WARNING This is a usual driving condition. When a malfunction is de-
tected twice in two consecutive driving cycles (two trip de-
tection logic), the MIL will light up to inform the driver that a
malfunction has been detected.
The following malfunctions will light up or blink the MIL in
the 1st trip.
• Misfire (Possible three way catalyst damage)
• One trip detection diagnoses

All components and systems should be monitored at least once by the OBD system.
• The B counter will be cleared when the malfunction is detected once regardless of the driving pattern.
• The B counter will be counted up when driving pattern B is satisfied without any malfunction.
• The MIL will go off when the B counter reaches
3. (*2 in “OBD SYSTEM OPERATION CHART”)

Driving pattern C means the vehicle operation as follows:
The following conditions should be satisfied at the same time:
Engine speed: (Engine speed in the freeze frame data) ±375 rpm
Calculated load value: (Calculated load value in the freeze frame data) x (1 ±0.1) [%]
Engine coolant temperature (T) condition:
• When the freeze frame data shows lower than 70 °C (158° F), “T” should be lower than 70 °C (158° F).
• When the freeze frame data shows higher than or equal to 70 °C (158° F), “T” should be higher than or equal
to 70° C (158 °F).
Example:
If the stored freeze frame data is as follows:
Engine speed: 850 rpm, Calculated load val ue: 30%, Engine coolant temperature: 80°C (176° F)
To be satisfied with driving pattern C, the v ehicle should run under the following conditions:
Engine speed: 475 - 1,225 rpm, Calculated load value: 27 - 33%, Engine coolant temperature: more than 70°C
(158 °F)
• The C counter will be cleared when the malfunction is detected regardless of vehicle conditions above.
• The C counter will be counted up when vehicle conditions above is satisfied without the same malfunction.
• The DTC will not be displayed after C counter reaches 80.
• The 1st trip DTC will be cleared when C counter is counted once without the same malfunction after DTC is stored in ECM.
